could someone explain to me the differences in bolt design with the newer A-Bolts versus the older A-Bolts? My A-Bolt is from 1990 and the bolt appears to be more cylindrical, whereas, the newer A-Bolts seem to have a hexagonal bolt shape with flat surface areas. Is there really any difference in rifle performance? is the newer bolt design an improvement or is it the pretty much the same?
